Species of coffee plant

Coffea canephora (especially C. canephora var. robusta, so predominantly cultivated that it is often simply termed Coffea robusta, or commonly robusta coffee) is a species of coffee plant that has its origins in central and western sub Saharan Africa. It is a species of flowering plant in the family Rubiaceae. Though widely known as Coffea robusta, the plant is scientifically identified as Coffea canephora, which has two main varieties, robusta and nganda. Coffea robusta represents between 40% and 45% of global coffee production, with Coffea arabica constituting most of the remainder. There are several differences between the composition of coffee beans from C. arabica and C. robusta. Beans from C. robusta tend to have lower acidity, more bitterness, and a more woody and less fruity flavor compared to C. arabica beans.

Robusta is a species of flowering plant in the family Rubiaceae. Though widely known by the synonym Coffea robusta, the plant is currently scientifically identified as Coffea canephora, which has two main varieties, C. c. robusta and C. c. nganda. and contains less sugar (3—7% compared to arabica's 6—9%). As it is less susceptible to pests and disease, robusta needs much less herbicide and pesticide than arabica.

C. canephora grows indigenously in Western and Central Africa from Liberia to Tanzania and south to Angola. It was not recognized as a species of Coffea until 1897, over a hundred years after Coffea arabica. In 1927 a hybrid between robusta and arabica was found in Timor. This strain was subsequently used to breed coffee rust resistant plants. and is less susceptible to disease than arabica coffea. It represents 43% of global coffee production, with arabica constituting the remainder except for the 1.5% constituted by coffea liberica. It is mostly grown in Vietnam, where French colonists introduced it in the late 19th century, though it is also grown in India, Africa, and in Brazil, where the conilon variety is widely grown. In recent years, Vietnam, which produces mostly robusta, has become the world's largest exporter of robusta coffee, accounting for over 40% of the total production. Roasted robusta beans produce a strong, full bodied coffee with a distinctive earthy flavour, but usually with more bitterness than arabica due to its pyrazine content. Since arabica beans are believed to have smoother taste with more acidity and a richer flavour, they are often considered superior, while the harsher robusta beans are mostly used as a filler in lower grade coffee blends.
